Introduction

In a surprising turn of events for enthusiasts clinging to the Itanium architecture, the upcoming release of GCC 15 has announced plans to reintroduce Linux support for Intel's original 64-bit processors. This development comes after a code patch accepted from esteemed developer René Rebe of ExactCODE, sparking a glimmer of hope for those still operating on the Itanic.

A Nostalgic Wave for Itanium Users

Yes, you heard that right! While this may not excite the mainstream tech community, it certainly sends a wave of nostalgia through the small yet dedicated circle of Itanium users. It’s essential to clarify that this support is primarily for systems running Linux. If you're still using HP-UX or OpenVMS, you may need to look elsewhere for solutions.

GCC Development Status

Currently, the GCC team is still working with version 14.2, with the much-anticipated release of version 15 on the horizon. However, it is crucial to note that while GCC 15 will allow for the compilation of new programs for Itanium-based systems, it will not restore the capability to build new Linux kernel versions, especially after Kernel 6.7 definitively dropped support for Itanium.

The End of an Era

Intel has long ceased production of IA-64 processors, and HP has also stepped away from selling new Itanium hardware. Still, for those who have managed to keep their Itanium systems alive within a Linux environment, the GCC 15 update assures continued compatibility in compiling binaries, albeit in a landscape where the architecture is considered almost legacy.

Emulation Hopes

Adding to the conversation, some tech enthusiasts believe that a full-featured FOSS emulator capable of running IA-64 virtual machines could do wonders for the community. Historically, emulation efforts, like the one initiated by Simics, have hinted at the untapped potential of these legacy systems. There even exists a partial CPU emulator known as HP's "ski" instruction set emulator, alongside some tools for running Windows binaries—so there’s hope yet for the resilient emulation fanatics ready to dive into a niche endeavor.

Conclusion

In summary, while the Itanium architecture may have faced significant setbacks over the years, GCC 15's renewed support for Linux serves as a temporary lifeline. This move not only provides crucial assistance to remaining users but also stirs conversations about the longevity and adaptability of technology, even against the odds. Will this newfound support inspire a renaissance for Itanium enthusiasts? Only time will tell!
